The all-Europe equivalent is ENTSO-E[1], which has down to 15-minute granularity (depending on operator I think) data for every generation unit in Europe.
There's a similar platform for the gas network too[2] - only daily data but it does have a map interface where you can see the main transmission pipelines across the continent.
I work in energy markets analytics, so grab data from these on a regular basis for SMEs.
